| Summary: | I present a scheme to obtain a 2 to 40 GeV low emittance muon beam, not
requiring cooling and within today's technological resources, to be used for
early commissioning of muon accelerator projects, or alternatively dedicated
muon and neutrino parameter measurements. In particular, a muon rate of 5x10^4
mu/s in a normalized transverse emittance of 5 um at 22 GeV, and energy spread
of 1 GeV obtained from O(10^11) e+/s on target at 44 GeV. This emittance is
below the expected results of advanced emittance cooling techniques for muons
produced from protons-on-target, and represents an alternative for the duration
of complete muon cooling studies. The scheme has beam designed to adjust the
muon beam energy in the GeV energy range to the needs for precise parameter
measurements of muons and neutrinos. Although the rate is small compared to
other muon sources, it does not seem to represent a big limitation for its
usage. Furthermore, the muon rate could be in principle increased
proportionally to the availability of higher positron rates, already foreseen
for future collider projects. |
